LAMP.

Specification of Letters Patent.

Patented June e, 1911.

Application filed lheeember 1D. 1910. Serial No. 596,700.

To all whom it may concern:

Be= it known that I, VVINFRED Gr. BowEN,-- a citizen of the United States of America, residing at Detroit, in the county of Wayne. and State of Michigan, have invented certain new and useful Improvements in Lamps, of which the following is a specititration, reference being h accompanying drawings. V

The invention relates to new and usetul improvements in. lamps and consists in the construction of a lamp intended particularly as a rear light vfor srnall boats, for which use the construction herein illustrated is particularly designed.

The invention consists in the construction,` arrangement and combination of parts hereinafter. specifically forth in the claims. l

Inpthe drawings-Figure 1 is a perspective view of a portion of the deck of a launch, the deck being?r partly broken away to illustrate my lamp extended -to its upper position, vas inpuse; Fig. 2 is a sectional elevation of the same;` and Fig. 3 is a section similar to Fig. 2, into the cup, as when 'not in use.

A represents the deck at the stern of a launch', and in this deck at the point where the rear light is to be located I cut a hole and in the hole place a cup B. This cup is preferably supported by atla-nge u, at its upper' end, which rests on. the surface of the deck, and is secured thereto by screws electric lampalthough prevent vibration.`

.or in any 'suitable manner. end of the cup I preferably form a sleeve .the IJ' of the cup, -lwater-tight. When At the lower GsurrOunding the `central aperture in the bottom of the cup, whichwsleeve on opposite Sides is preferably provided with a curved locking slot (l having a locking shoulder e. Sliding through the sleeve a is thc standard C which at its upper end carries a lamp l), .the lamp as 'shown being preferably an it may be a lantern. The lamp preferably fits quite snugly within `the cup, at least at its bottom, so as to At the top the lamp is provided with a. top- E having a downwardly-extending flange h which engages 'over'an upwardly-extending Hapgei at the top of the cup, so as to form a closure for preferably substantially the lamp is an electric damp, the standard G is hollow and through it may pass the wires F to carry the current ad therein to the A showingthe lamp lowered,

to the bulb G which is within the lamp. The lower end of the standard is provided upon o )posite sides with pins k which, whetie lamp is raised to the position shown in Figs. l and 2, may engage in the locking notches e and hold it in such raised posit-ion. 7When the lamp is raised, for the purpose of steadying it to prevent vibration and also for the purpose of closingr the cup, l arrange the disk or collar H which rests on a. shoulder 'l on the standard.' As'the standard is lifted the shoulder I strikes the disk lvl and lifts 'it -to the top of the cup, as shown in Fig. Q, and thus serves the purpose described, in the extended position of the lamp. lVhcn the lamp is lowered into the cup by disengaging the pins le from the locking notches c the standard` will be lowered and the collar H will descend within the cup\ until it strikesthe bott-0in, where it vwill remain stationary while the upper portion of the standard moves through it` freely. t'

The operation of the device will be obvious from the description already given.

flint I claim as new is:

1. The combination with ,a deck having an aperture therethrough oi a support be low said aperture7 a lamp adapted' to fit pinto said aperture and a standard having the support below the i deck for holding the lainp above the deck.

Q. The combination of a lamp. a cup for receiving the lamp, an extension support for the lamp adapted tosupport the saine above the cup -or to permit it, to be lowered therein.y and a top on the lamp forming a closure for the cup.

3. The conibirnxtion of ay lamp. a cup for yreceiving` the lamp` u standard forming4 an extension support for the lamp, means or holding the lmnp above the `cup and a closure for the cup iii the extended position of the standard.

4. The combination of he sup'liiorted in an aperture of a deck, a bearing in the lower part thereof, a lamp adapted to enter the cup, a standard for the lamp, and a device at the lower part of the "11n-cans for engaging a cup adapted to bearing.

standard adapted to be supported in said 5. The combination of a cup having an" bolmn'l of the au?, means at the lower end Inl 'testimony wherof I affix my signature of the standard or ongngmg Wlth the bot- 1n presence of two Wltnesses. tom of thv cup t0 support the lamp 1n the extended positlon, 'a collar around the WINIRED G' BOWEN' 5 standard and means on the standard for Witnesses: raising the collar to the upper part of the JAMES P. BARRY, cup as the standard -is lifted. MARION B. FAY.
